How to Make Grilled Cheese and Tomato Soup Casserole

Step 1: Prepare the Bread and Cheese Layers

Start by buttering the slices of bread on both sides, then toast them lightly in a skillet until golden brown. Layer the toasted bread slices in your casserole dish, adding a generous layer of shredded cheddar cheese between each slice to build that classic grilled cheese texture.

Step 2: Mix the Tomato Soup

In a medium bowl, whisk together your canned or homemade tomato soup with milk or cream and dried herbs like basil and oregano. This mixture will soak into the bread, infusing it with richness and depth.

Step 3: Assemble and Pour

Pour the tomato soup mixture evenly over the layered bread and cheese in the casserole dish. Press lightly so the bread absorbs the tomato soup but doesn’t become soggy. Finish by sprinkling a layer of grated Parmesan cheese on top for a golden crust.

Step 4: Bake Until Bubbly and Golden

Place the casserole in a preheated oven at 375°F (190°C) and bake for 25-30 minutes until the top is bubbly and golden brown. Let it rest a few minutes before serving to thicken up and enhance the flavors.

Pro Tips for Making Grilled Cheese and Tomato Soup Casserole

• Use Sturdy Bread: Thick, firm bread ensures the casserole holds its shape and soaks up the tomato soup without falling apart.
• Don’t Over-soak: Pour the soup gently and avoid drenching the bread to keep a nice texture contrast between toastiness and creaminess.
• Cheese Quality Matters: Choose a flavorful, good melting cheese like sharp cheddar for that iconic grilled cheese taste.
• Let It Rest: Allow the casserole to sit for 5-10 minutes after baking to set and cool slightly, making it easier to slice.
• Add Crunch: For a crunchier topping, mix breadcrumbs with Parmesan cheese and sprinkle on top before baking.
